So it's taken forever but I finally made some cards!
This is a Waterfall card (also known as Movement card) with a Wedding theme. To give the card movement, you'd gently pull the two cords at the bottom of the card to make each image flip up to reveal another image beneath. Images are bouquet, wedding dress, tiered wedding cake, champagne flutes.
This shows the movement of the card when pulling the two cords at the base of the card, and it slowly allows the sentiment to be displayed that is currently hidden by the images.
